【摘要】 该研究对实验性缺硒病仔猪检测了两种血清酶活性。结果表明,血浆谷胱甘肽过氧化物酶活性与血硒含量呈正相关（r=0.563）;实验组与对照组相比,血浆谷胱甘肽过氧化物酶活性明显降低,而血清乳酸脱氢酶同功酶的LDH₅活性却显著升高。更多还原

【Abstract】 Two serum enzymes activities were determined in experimental selenium deficient pigs. The results indicated that serum glutathione peroxidase activity was positively correlated （r=0.563） with blood selenium concentration. The diseased group compared with the control group, serum glutathione peroxidase activity was markedly decreased, but serum LDH₅ activity was increased.更多还原
